2. For an address in another data area, the number of addresses from the be-
ginning of the search is written to D+1. For example, if the address contain-
ing the minimum value is IR 114 and the first word in the search range is
IR 014, then #0100 is written in D+1.
If bit 14 of C is ON and more than one address contains the same minimum val-
ue, the position of the lowest of the addresses will be output to D+1.
The number of words within the range (N) is contained in the 3 rightmost digits of
C, which must be BCD between 001 and 999.
When bit 15 of C is OFF, data within the range is treated as unsigned binary and
when it is ON the data is treated as signed binary. Refer to page 27 for details on
signed binary data.

Caution If bit 14 of C is ON, values above #8000 are treated as negative numbers, so the
results will differ depending on the specified data type. Be sure that the correct
data type is specified.
Flags ER: Indirectly addressed DM word is non-existent. (Content of DM word is
not BCD, or the DM area boundary has been exceeded.)
The number of words specified in C is not BCD (000 to 999).

Limitations Data of S must be hexadecimal.
N must be BCD from #0001 to #0064.
D and D+N+1 must be in the same data area.
Description AVG(––) is used to calculate the average value of S over N cycles.
When the execution condition is OFF, AVG(––) is not executed.
